TEMPORARY BINDER. v

Application iiieaseptembere, 1923. serial No. 661,17?.

This invention relates to temporary binders or loose lea-lf binders.

Objects ot this invention are to provide a loose leal binder which may berloclted in any one ot several adjusted positions to accom- .niodate various thicknesses of included lea-ves, which will securely retain the parts in their adjusted position against accidental or unwarranted motion, which may be manuiactnredl with great facility, and which is ot" 4inexpensive construction; Y

Further objects are to provide a loose leaf binder in which the two main elements may be locked by means permanently carried by the binder, ii desiredl` in which the locking 'mechanism and the manipulating device-s therefor occupy a minimum of space, and in which a positive wedging grip is secured by the locking i'nechanism.

Einbodiinents ot the invention are shown in the accompanying drawings, in which:

Figure 1 is a plan view of the binder with portions broken away to illustrate the mterior construction. 1

Figure 2 is a siectional'view lon the line iZ- -2 oi Figure 1'.

Figure et' is a sectional view on the line t--t of Figure 1.

Figure is an enlarged detail ot a portion of the binding means.

'Figure (i is a side elevation partly in section of a iurther form ot locking means.

v`the invention will be described. The temporary bindericoinprises a bottoni portion which consists ot a tubuiarmetal member 1v from which uprights,`preferably of the form These 'up-` of cylindrical posts 2 ext-end. rights may, it-desired, be made of a plurality ot pieces adapted to be screwed together in a well known manner. The loose leaves 3 lare adapted to be threaded upon the' posts 2. A top member consistingof a tubular sheet-metal channel 4: is provided with a pair-'of apertures o through which the post 2 may be readily passed.v ri`hus after the leaves have been threaded upon, the posts the top 4 is slipped into position and pressed firmly down against the leaves and locked.

The locking means comprises a plate 6v which is loosely held within the channel 22 may be provided intermediate the ends of 'l each ot the channel members.

`section l by means ot a rivet 7 for instance,

and is provided with a pairof outwardly and upwardly extending terminalfportions C5-8. rFliese portions are secured to the bar 't and are notched. or curved, as indicatedat E) in Figure 1, so as 'to conform slightly to Vthe curvature of the posts 2. The spacing ot the posts and of the locking tongues 8 is such that the tongues may freely slide upon the posts in normal position.` i

In order to torce the posts into lengagement with thetongues 8,l a sliding plate or binding plate 10 is provided and is swivelly joined to an adjusting or binding screw 11.` rihis binding' screw 11,'as may be seen from n. i* igureb, may be provided with a shoulder "12 loosely Areceived in a cut-out portionl in ready ttor operation and self-contained without the' necessity of employment of ant additional instrument. Figuresl to showing the hrst forni ot The'binding screw is-tlireaded through a block 17, (see Figure 2). cured by means of rivets 18 (Figure 1) which passthrough the outer` shellv orchannel land securely fix the block in' position.

A somewhat similar block '19 is provided for Athe other end of thechannel 4- and is similar- 95 ly riveted in position although, obviously, this block is notprovided with a transverse aperture. Hinge membersQOare received in slots within the blocks 17 and 19 and are retained in position by ineans'ot the rivets 18. 100

fFliese hinge members carry the pintle rod If desired, an additional hinge member The pintle4 rod is attached to the usual manner.

Any desire-d means may be employed for finishing the ends of the channel member 4:.

This block is se- 9o upper cover 23 in the 1.05

:withthe spring tongues 8.

lowsz-When it is desired to lock the cover y in position, the thumb nut 16 is rotated'and forces the plate l into engagement with the right-hand face of the right-hand post 2. lhis forces the post against `'the tongue 8 and, due to the slight sliding motion of the plate 6, forcesthe other tongue 8 against the other post. rllhe last-mentioned post is engaged by the left-hand face of the aperture of the channel member l as such channel member is drawn Ato the right in Figure 2 by the action of the screw and thus theposts are forced into firm binding engagement Obviously, vany Y tendency toslide the cover from the posts lwill result in a slight rocking motion of the tongues 8 causing them to bind more tightly against the posts 2.

Figure 6 shows a vention in which the channel member 26 is :similarlyprovided with a bearing block 27 through which., is threaded the clamping screw 28 adjustable by a manipulating nut V29 or key. if desired. rIhis clamping screw terminates in an enlargement or shoulder 30 which bears directly against one of the posts 2. This construction replaces the bearing slide l0 (see Figure 5) of that formerly described andinay cooperate with a type of I locking bar. similar to that indicated at 6 in lligure 2. ,Howeven a further type of locking bar, indicated generally at 3l, is illustrated in Figure 6 and comprises a strap-like body portion providedk with integral upwardly turned terminal tongues 32.,

It is to be understood that although the base vmember is referred to as equipped with upwardly projecting posts `and the topfinem-I Vber as the removable member, that obviously the members may be reversed without deypartingfrom the spirit ofthe invention. These terms, therefore,as usedin the claims,

are not intended to limit rthe invention but are used merely forthe sake of clearness.Y

It is further to be noted that the bottom member may be made slightly longer than further form of theV in- Y the top member so as to offer a certain'degree of vprotection for the adjusting nut.

It will thus be seen that a temporary binder or loose leaf binder has been provided in'which the removable or top member is securely clamped inposition upon the upright posts in a simple and effective manner, in

A loose leaf binder comprising a bot-k tom member having a pair of upwardly extending posts, a tubular top member having a pair of apertures therethrough for loosely receiving said posts, a locking bar normally free to move relatively to said'posts located interiorly ofsaid tubular member and having terminal upwardly and outwardly eX- t'ending locking tongues and ,externally` manually operable means extending into said tubular member for forcing said posts towards each other and into engagement with said locking tongues.
